Belated mother's day gift from ko ko

Today ko ko give me a surprise from his school. His computer teacher has gave him a card for him to decorate and give to mummy and papa as mothers's day and father's day gift :p Before that he was upset because he has nothing for me on mother's day hence today he is very excited to have something for me.

Still remember the mother's card from di di ? behind the card there was a green paper attached which I thought di di suppose to draw something on it but he didn't complete his work due to he has absent few days from school. However the truth has revealed when teacher gave a surprise by sent me a sms requested parent to write something on that paper and let the child brought back to school on Monday, teacher will read aloud in the class. What a special request and surprise huh ?

The following is what I write:

亲爱的俊宇，

谢谢你为妈妈做了一张好漂亮的卡片。妈妈很开心！你好棒喔！妈妈爱你！
